- the instant film is constantly pressed from the state where all the instant film remains in the instant film pack to the last one. In order to do so, a spring member with a constant spring constant or higher must be used. As a result, the parts of the film pressing portion become large, which leads to an increase in the size of the printer.
- the pressing force fluctuates greatly between the state of a large number of remaining instant films and the state of the last one.
- the flat state of the instant film varies depending on the remaining number of sheets, which affects the transport performance of the pair of transport rollers, and may eventually degrade the image quality.
- the pressing force of the film pressing portion fluctuates greatly, the instant film may be caught in the ejection port.
- the spring constant of the spring 79 constituting each of the film pressing portions 22a to 22d is reduced. can do. Therefore, the components of each film pressing portion 22a to 22d can be made smaller. Further, by reducing the spring constant of the spring 79, it is possible to reduce the fluctuation of the pressing force due to the remaining number of the instant films 28, thereby preventing deterioration of the image quality.
- the spring constants of the springs 79 constituting the respective film pressing portions 22a to 22d can be made different. That is, the degree of freedom in designing the spring constant of the spring 79 constituting the film pressing portions 22a to 22d is increased, and the variation in the pressing force due to the remaining number of instant films 28 can be further reduced.
- a coil spring is used as the spring 79, but it is not limited to this, and other spring members such as leaf springs may be used. Further, in the above embodiment, an example of application to a digital camera with a printer is given, but the present invention is not limited to this, and may be applied to a single printer device.
