In an incubator according to the present invention, physical condition of a newborn is less likely to get out of order though a hand insertion window can easily be opened by operation with, for example, an elbow instead of a hand. A latch in a latch mechanism has a spiral face that extends to at least part of the periphery of a rotation shaft that extends along a side of a newborn chamber. A releasing member in the latch mechanism presses the spiral face of the latch by movement along the side of the newborn chamber and rotates the latch from a holding position to a releasing position for a hand insertion door. In addition, even if the latch in the latch mechanism rotates about the rotation shaft between the holding and releasing positions for the hand insertion door, the releasing member does not rotate.

1. An apparatus comprising: a hand insertion window formed in a side of a newborn chamber;a hand insertion door that opens and closes the hand insertion window by rotation;a latch mechanism that holds the hand insertion door in a closing position for closing the hand insertion window; wherein the latch mechanism includes a latch and a releasing member,the latch has a rotation shaft extending along the side and enabling rotation between a holding position for the holding of the hand insertion door and an releasing position for releasing the holding of the hand insertion door, and a spiral face extending to at least part of a periphery of the rotation shaft; andthe releasing member is movable along the side, and presses the spiral face by movement to cause the rotation of the latch from the holding position to the releasing position; andan opening mechanism configured such that in the course of the rotation of the hand insertion door in the direction in which the hand insertion window is closed, the opening mechanism comes into contact with the hand insertion door before the hand insertion window is closed, and thereby urges the hand insertion door to cause the rotation in the direction in which the hand insertion window is opened, wherein a packing is attached to an internal edge of the hand insertion window and the packing serves as the opening mechanism. further wherein the packing has a thicker portion and the thicker portion serves as the opening mechanism,wherein the latch has a pressed portion that is pressed by the rotation of the hand insertion door, and thereby causes the rotation from the holding position to the releasing position, andthe pressed portion is made of impact-absorbent material. 2. The apparatus according to claim 1, further comprising a helical compression spring urging the releasing member in a direction opposite to the direction in which the spiral face is pressed. 3. The apparatus according to claim 1, wherein the impact-absorbent material is silicone rubber. 4. The apparatus according to claim 1, wherein the latch mechanism includes: an urging member for urging the rotation of the latch from the releasing position to the holding position; anda braking member for braking slowing the rotation of the latch. 5. The apparatus according to claim 4, wherein the latch mechanism includes a latch base plate supporting the latch and the releasing member, and the braking member is a spacer disposed between the latch and the latch base plate and around the rotation shaft. 6. The incubator according to claim 1, wherein a packing is attached to an internal edge of the hand insertion window, and the packing serves as the opening device. 7. The incubator according to claim 6, wherein the packing is made of silicone rubber. 8. The incubator according to claim 6, wherein the packing has a thicker portion, and the thicker portion serves as the opening mechanism. 9. The apparatus according to claim 8, wherein disposed on the thicker portion is a projection for preventing the packing from being erroneously attached, and the thicker portion and the projection serve as the opening mechanism. 10. The apparatus according to claim 9, wherein a rotation shaft for the rotation of the hand insertion door is inserted in a helical coil spring, and the thicker portion, the projection, and the helical coil spring serve as the opening mechanism. 11. An apparatus comprising: a hand insertion window formed in a side of a newborn chamber; a hand insertion door that opens and closes the hand insertion window by rotation;a latch mechanism that holds the hand insertion door in a closing position for closing the hand insertion window; wherein the latch mechanism includes a latch and a releasing member,the latch has a rotation shaft extending along the side and enabling rotation between a holding position for the holding of the hand insertion door and an releasing position for releasing the holding of the hand insertion door, and a spiral face extending to at least part of a periphery of the rotation shaft; andthe releasing member is movable along the side, and presses the spiral face by movement to cause the rotation of the latch from the holding position to the releasing position; anda braking mechanism configured such that a portion of door around the shaft is not completely circular in cross section, so there will be a separation between the door and the braking mechanism, whereinwhen the door is moved to the open position, there is a time that there is no connection, and from the moment that the surface of the door makes contact with the braking mechanism to the open position, the braking mechanism is then capable of brake rotation of the door, andthe braking mechanism is located next to the shaft of the door. 12. The apparatus according to claim 11, wherein a portion around a rotation shaft for the rotation of the hand insertion door has a cross-section that is not completely circular, and the cross-section comes into contact with the braking mechanism in the course of the rotation. 13. The apparatus according to claim 12, wherein the braking mechanism is elastically deformable, and by the elastic deformation, the braking mechanism absorbs pressure applied due to the contact.
