Abstract: Dot codes (i.e., code images) are printed on a paper sheet. Each dot code has a variable part and a fixed part. The variable part is specific to the dot code, whereas the fixed part is common to the dot codes. The fixed part represents an audio mark that informs a user when the user should move a dot code reader (i.e., a code image reading apparatus) to read the next dot code to read the same. As the user moves the dot code reader over any dot code, the reader reproduces an audio message from the variable part and then an audio mark from the fixed part. The user hears the audio message and the audio mark through an earphone. Upon hearing the audio mark indicating that the audio message has been completely reproduced, the user may move the reader to the next cod code.

A shield is situated upstream of the upstream mark and serves to block downstream passage of the charged particle beam except to illuminate the upstream mark or a portion of the upstream mark. The upstream mark can be situated on the reticle or on a mark member situated in the reticle plane.

As the object is moved relative to the surface, the locations of these distinct features relative to the photosensing element move.

Abstract: A radiation image read-out apparatus including a lens array and a line sensor for reading an image recorded on a stimulable phosphor sheet provides a read-out image of high quality which is free from a spurious pattern due to non-aperture regions of the lens array. A first memory stores an image signal representing the image recorded on the stimulable phosphor sheet. Spurious pattern signal calculating means calculates a spurious pattern signal based on positions of the non-aperture regions on the lens array. The spurious pattern signal is stored in a second memory. Image modification means reads the image signal and the spurious pattern signal from the first and second memories to calculate a processed image signal free from any spurious pattern signal on a pixel-by-pixel basis. The spurious pattern signal may instead be obtained by causing the apparatus to read a uniform radiation image recorded on the stimulable phosphor sheet.

The line sensor comprises a pair of one-dimensional CCD image sensors. Light receiving regions of the one-dimensional CCD image sensors are located close to each other with respect to a direction normal to the length direction of the linear area of the sheet and with a fine gap intervening between the light receiving regions.
