BOOK TYPE KEY INPUT DEVICE

摘要

PURPOSE:To decrease the number of times of turn-over of book sheets by constituting a processing circuit which reads the input information with the spread page information and operating keys so that the input information supplied through operating holes of keys at the same area of a part of an even or add page has the same function when any one of pages of the book sheet is spread. CONSTITUTION:The 10 keys are allocated for primary jobs to each of the 1st rows (a) of odd pages (left side of a spread page) between the 1st and 30th pages. While 20 keys for primary articles are allocated to every 1st and 2nd rows (b) of even pages (right side of a spread page) respectively. In addition, the keys for customers are allocated to the areas excepting the 1st row of each odd page and the 1st and 2nd rows of each even page between the 16th and 30th pages. In such constitution, the primary 10 jobs and primary 20 articles are always shown on any page of a book. Thus an operator can search a desired customer key among the 16th-30th pages just with a single operation.
