[Prior Art]

 For example, an electronic cash register has an upper case mounted on a lower case, a key input section on the front side of the upper case, a display section on the right side of the rear, and a rear left side on the lower case. Some printers have a structure in which the printer cover is removable or can be opened and closed. In this case, on the lower case below the printer cover, the pair of roll paper holding columns for holding both ends of the roll paper for receipt and the roll paper held by these column for holding roll paper may be used. There is a printer that prints out the printed paper and issues a receipt. When the printer cover is opened, new roll paper can be held on the roll paper holding column.

By the way, in such an electronic cash register, generally, when the sales contents are sequentially written in a RAM (random access memory) provided in the case, for example, when the sales contents for one week or one month are settled. The payment statement is created by reading from RAM. In this case, in order to prevent the contents of sales written in RAM from being erased, a battery for memory backup is stored in the case. Since such a battery is a consumable item, it can be easily replaced. It is desirable to store it in a place. Therefore, conventionally, a memory backup is provided near the roll paper holding column that also holds the roll paper for receipt, which is also a consumable item, that is, on the lower case below the roll paper held by the roll paper holding column. Holds the battery of.

However, in such a conventional electronic cash register, when the battery for memory backup is replaced, the roll paper held by the roll paper holding column must be removed. Therefore, there was a problem that battery replacement work was troublesome.

This is because the battery for memory backup is stored on the lower case below the roll paper held by the roll paper holding column. Then, although it is near the roll paper holding column that holds the roll paper, if the batteries can be stored in a place other than the lower case below the roll paper held by the roll paper holding column, if the roll can be stored. It is possible to replace the battery without removing the roll paper held by the paper holding column. The problem of this invention is in the vicinity of the roll paper holding column for holding the roll paper, but it is possible to install the battery on the lower case below the roll paper held by the roll paper holding column. Is to

For example, in an electronic cash register equipped with a printer for issuing receipts, a pair of roll paper holding columns for holding both ends of the roll paper for receipt are provided on the left and right of the rear left part on the lower case. It is a thing. (2) A battery accommodating portion provided on a surface of the pair of roll paper holding portions, which is closer to the side wall of the lower case, on a surface opposite to the roll paper holding side surface. For example, on the left side of the pair of roll paper holding columns provided on the left and right of the rear left part on the lower case of the electronic cash register equipped with a printer for issuing receipts (the one close to the left side wall of the lower case). This is a battery storage unit provided on the left side of the support for holding roll paper (the surface opposite to the surface on which the roll paper is held), and stores the battery for the memory backup.

[0007]

[Action]

 The operation of the means of this invention is as follows. Of the pair of roll paper holders, the battery storage section is provided on the side of the roll paper holder that is closer to the side wall of the lower case, opposite to the roll paper holder side. The batteries can be replaced independently of the retained roll paper. Therefore, the battery can be provided in the vicinity of the roll paper holding unit that holds the roll paper, but in addition to the lower case below the roll paper held by the roll paper holding unit.

【Example】

 1 and 2 show the essential parts of an electronic cash register of one embodiment. This electronic cash register has a structure in which a lower case 2 made of synthetic resin is placed on a cash drawer 1. A printer unit 3 is provided on the left rear portion of the lower case 2, and a printer (not shown) for issuing receipts is arranged in the printer unit 3. The printer unit 3 is covered by a printer cover 4 which is provided on the lower left part of the lower case 2 at a rear part thereof so as to be removable or openable. A pair of roll paper holding columns 5 and 6 for holding both ends of a roll paper for receipt (not shown) are integrally provided on the left and right of the rear portion of the printer unit 3. The height of the roll paper holding columns 5, 6 is higher than the upper edge 2b of the left side wall 2a of the lower case 2 to some extent.

A battery accommodating portion 11 is integrally provided on an upper portion of the left surface (the surface opposite to the surface on which the roll paper is held) of the left roll paper holding column 5. Since the height of the left roll paper supporting column 5 is higher than the upper edge 2b of the left side wall 2a of the lower case 2 to some extent, most of the battery storage section 11 is located at the upper end of the left side wall 2a of the lower case 2. It is provided above the edge 2b. The battery accommodating portion 11 includes a side plate 12 integrally provided on the left side of the left side roll paper holding column 5, and a substantially L-shaped flat guide plate provided at the front and rear ends of the side plate 12. 13 and an engaging hole 14 provided at a predetermined position of the side plate 12, the upper part and the left part are open. A battery box 15 is inserted into and fixed to the battery storage unit 11 from above. The battery box 15 includes a battery box main body 17 having an opening 16 on a predetermined side surface, a lid 18 attached to the opening 16 of the battery box main body 17 from above, and a predetermined lower surface of the battery box main body 17. The structure is provided with an engaging piece 19 provided at a position, and is electrically connected to a main circuit board (not shown) via a lead wire 20.

When fixing the battery box 15 to the battery storage unit 11 of the electronic cash register, the battery box 15 is inserted into the battery storage unit 11 from above with the lid 18 of the battery box 15 facing left. When the battery box 15 is inserted and engaged with the engagement hole 14 of the battery storage portion 11 while elastically deforming the engagement piece 19 of the battery box 15, the battery box 15 is fixed in the battery storage portion 11. In this state, most of the lid 18 of the battery box 15 is located between the two guide plates 13 1 of the battery housing 11 above the upper edge 2b of the left side wall 2a of the lower case 2.

Next, when accommodating the memory backup battery 21 in the battery box 15, first, the guide plates 13 of the battery accommodating portion 11 are arranged above the upper edge 2b of the left side wall 2a of the lower case 2. The lid 18 of the battery box 15 located between them is pulled up and removed, and the opening 16 of the battery box body 17 is opened. Next, for example, three batteries 21 are housed in the battery box body 17 through the opened opening 16. Next, the removed lid 18 is attached to the opening 16 of the battery box body 17 from above, and the storage of the battery 21 in the battery box 15 is completed. In this state, the battery 21 is stored in the battery storage portion 11 via the battery box 15. When replacing the battery 21, almost the same procedure is performed.

As described above, in this electronic cash register, the battery storage section 11 is provided above the left surface (the surface opposite to the roll paper holding side) of the left roll paper holding column 5. Therefore, the battery 21 can be replaced regardless of the roll paper held by the pair of roll paper holding columns 5 and 6, thus facilitating the battery replacement work. Moreover, since most of the battery housing 11 is provided above the upper edge 2b of the left side wall 2a of the lower case 2, when the battery 21 is replaced, the left side wall 2a of the lower case 2 is an obstacle. Therefore, battery replacement work becomes even easier.
