The cartridge holder has a holding space and a holder latching component. The holding space is capable of holding a pharmaceutical cartridge. The latching receiver is configured to latch or release the holder latching component according to whether the cartridge holder is closed or open. The driver is configured to automatically release a latching of the latching receiver and the holder latching component. The manipulation component is configured to manually release the latching of the latching receiver and the holder latching component by moving the latching receiver upon being subjected to external pressure. The driver or the manipulation component is configured to release the latching between the latching receiver and the holder latching component.

Pharmaceutical injection device

The pharmaceutical injection device of the present invention comprises a cartridge holder, a main case, a piston, a motor, an opening component, an open/closed detection switch, and a controller. The motor drives the piston in either an insertion direction in which the piston is inserted into a pharmaceutical cartridge, or a pull-out direction in which the piston is pulled out of the pharmaceutical cartridge. The opening component opens the cartridge holder in conjunction with the movement of the piston in the pull-out direction. The open/closed detection switch detects whether the cartridge holder is open or closed. When the open/closed detection switch detects that the cartridge holder is open, the controller controls the motor so as to stop the piston.
