Abstract

PURPOSE:To display counter interlocking with recording apparatus with a simple constitution by providing a cassette with an electrochromic display for counter display and input contacts for an electric signal driving the display. CONSTITUTION:The electrochromic display (ECD) for counter display is provided with the input contact 103g inputting electric signals driving the ECD and a display part and upper and lower electrodes 103d, 103b, etc. are laminated on a substrate 103a. Two ECDs 103 are prepared and adhered turning the edge of a cassette housing 101 so as to be reversed each other. The cassette 1 having said constitution is set to a camera and the driving device is engaged with a hub 102a and contacted with a disc 102. Therefore, a signal to be counted is displayed on the display part of the ECD103 through the contact 103g as a colored numeral and observed through the window of a camera case. Even if the cassette is replaced on the way of display, the display is kept as it is by the storage characteristics of the ECD.

[However, in this case, if a recording cassette such as a film cassette or tape cassette is replaced midway through use without using all the recording media, it will become useless as a counter. It is desirable that the display device be completely removed. Accordingly, there have been examples of printing frames & on the backing paper of the film, such as the so-called 110 type film cassette, and discs, such as the magnetic disk cassette of Sony's Mavica (magnetic recording camera) system. There is an example in which a mechanical counter display device W like this is provided in an empty space of a cassette. However, the former example not only adversely affects the flatness of the film, but also cannot be applied to magnetic recording media due to the thickness of the backing paper, and the latter example cannot be easily viewed due to space constraints.

First, the detection circuit (204) operates to check the display status of each segment of the number display section of the FiCD. Due to the nature of ECD, electric charge is accumulated in a segment that is in a colored state, so it is necessary to detect whether the terminal voltage of that segment exceeds a certain value ((therefore, it is possible to determine whether a segment is colored or not). The count is determined and displayed by combining the skin colors of each segment.
