Description

[Detailed description of the invention] [Industrial application field] The present invention provides a door in the casing, and also provides a shelf for specially placing and storing a plurality of cassettes and a heater for keeping warm inside the casing. This invention relates to a cassette storage box equipped with a heat insulating heater.

[Conventional technology]

The above-mentioned cassette storage box with a heat-retaining heater is not only convenient for organizing the cassettes, but also improves the clarity of copies by feeding the copy paper from the cassette loaded in the copying machine and by heating the inside with a heat-retaining heater. This has the advantage of preventing moisture that can have an adverse effect on the paper, and allowing the copy paper to be kept in an appropriately dry state at all times.

[Problem that the invention attempts to solve]

However, in the past, the heat generation of the heat retention heater was artificially controlled, which resulted in people forgetting to stop the heat retention even though the cassette was not stored, or wasting the temperature needlessly. Sometimes I forgot to switch to the heat retention state and control it.

[Means for solving problems]

In addition to solving the above-mentioned drawbacks, the present invention aims to provide a cassette storage box with a heat-retaining heater that can easily dry copy paper uniformly. The box divides the internal space of the casing into a space for cassette storage shelves and a space for heat retention,
A heat-retaining heater is provided in one of the heat-retaining spaces, a cassette presence/absence detector is provided in the other shelf space, and the heating of the heat-retaining heater is controlled based on cassette detection information from the cassette presence/absence detector. It has characteristics.

[Effect]

According to the above-mentioned characteristic structure, a heat retention state is automatically obtained only when a cassette is present in the shelf arrangement space, and the entire shelf arrangement space can be uniformly kept warm by indirect heating.

〔Example〕

Hereinafter, embodiments of the present invention will be explained based on the drawings. Figs. 1 and 2 show a cassette storage box with a heat insulating heater. It is divided into heat retention spaces A and C and shelf arrangement space B, which will be described later, by partition walls 2 and 3.

It is not necessary to match the spacing between the cassette size display sections 11, and the front sections of the cassette size display sections 11 may be arranged in a concentrated manner near the upper end of the door 4, for example.

Further, inside the casing 1, as shown in FIG. 3, cassette size detectors 12 are provided for each shelf 7, and based on the detection results of these cassette size detectors 12, the The cassette size display section 11 is configured to display the cassette size.

Although a phototube switch or the like may be used as the cassette size detector 12, in this embodiment, a plurality of proximity switches _S1 to _S4 are used. The required number of proximity switches S ₁ to _{S 4} are installed at predetermined intervals on the inner end rising portion 7a of each shelf 7, while the front end of each cassette 8 is attached as shown in FIGS. 4 and 5. A detected part is formed by attaching a magnet 13 at a different position for each size, and by storing a cassette 8 in an arbitrary stage, a detection part is formed in the vicinity corresponding to the attaching position of the magnet 13. The configuration is such that only the switch (any one of the above-mentioned _S1 to _S4 ) is turned on and the size of the cassette 8 is detected.

SWs shown in FIGS. 2, 5, and 7 are detectors for detecting the presence or absence of cassettes 8.
When the cassette 8 is stored, it is turned on by the weight of the cassette 8 or by the magnet provided on the bottom surface of the cassette 8.
