Image display apparatus
First Claim
1. An image display apparatus for paging images on a display screen, comprising:
- memory means for storing a plurality of page images with image identification numbers;
display means for sequentially reading the page images from said memory means and for sequentially displaying the page images on a display by paging so that each page image replaces another page image on the display by successive line scanning with a specified display interval time;
display speed control means for specifying a display interval time per page image and the direction of paging;
timer means for measuring the elapsed display time per page; and
means for continuously sampling the display interval time specified by said display speed control means and for comparing a sampled value of display interval time with the elapsed display time measured by said timer means to continuously control the paging by said display means based on the results of said comparing.

Abstract
An image display apparatus that can ease the man-machine interaction when a user searches for a document in an electronic filing system, for example, through the image display apparatus. In a conventional electronic document filing system, it has been difficult to search for a document by inspecting or looking at the original document images shown on an image display screen. The difficulty comes from the lack in a capability of controlling the instantaneous display speed, an appropriate feedback to the user to synchronize the image paging, and a capability of showing the direction of paging. The image display apparatus disclosed here has a tactile feedback mechanism that tells the user the time a new image page is shown and that also tells him/her other status of the apparatus, like how busy it is, in terms of a tactile signal to the user'"'"'s fingers. The mechanism is installed in a mouse-like pointing device that tells the apparatus the speed of paging. By using this, the user can control the paging speed spontaneously and at the same time he/she can feel the paging through the tactile feedback, in addition to a kind of sound effect.
